Seventy-five years in the past this week, when Giuseppe Farina roared throughout the ending line to win the primary world championship grand prix at Silverstone, he did so in an Alfa Romeo 158 weighing – relying on fluids and which sources you employ – between 650 and 700kg. When Formulation 1 adopted a minimal weight for the primary time in 1961, the determine was set at 450kg.
Below the newest ruleset, groups have been struggling – be aware the quantity of unpainted carbon fibre on show – to hit the present minimal of 800kg. On the face of it, not a implausible advert for three-quarters of a century of scientific progress.
Clearly the determine of 800kg now consists of the motive force however even when considered via a extra rigorous prism, which entails going again to 1995 when the automobile and driver weight was first mixed, the ensuing determine makes for an unpleasant comparability: 595kg.
The distinction is 205kg. Previously three a long time solely the worth of Oasis gig tickets has inflated extra egregiously.
“We would all just like the automobiles to be lots lighter,” FIA single-seater director Nikolas Tombazis informed Motorsport.com. “Among the options being mooted [in terms of future powertrains] would result in considerably lighter automobiles, which is what everybody would love.
“It is a trade-off between financials, technological freedom and the way cutting-edge Formulation 1 is, environmental concerns, and pleasure.”
Round 100kg of the burden acquire got here because of adopting hybrid powertrains. The present minimal weight for a hybrid energy unit is 151kg – evaluate that with, say, a late Nineties 3-litre V10 which weighed between 90kg and 100kg.

Whereas the PU minimal weight of 151kg consists of the hybrid system, it doesn’t embrace the turbocharging mechanism or, extra considerably, the cooling system, which is vastly extra advanced than the plumbing required by a Nineties engine. The times of getting two easy radiators dealing with nearly all of warmth administration are lengthy gone.
Round 50kg of extra weight could be accounted for by security options reminiscent of stronger side-impact buildings and the halo. Intelligent engineering and design can mitigate the consequences of getting to withstand a stricter crash-testing regime however, to an extent, with extra energy comes weight.
Given the rising record of possible accidents averted by fashionable security options, this isn’t a component anybody smart in F1 would want to row again on.
The remaining 55kg or so of bloat is accounted for by a mixture of parts, a few of which it may very well be attainable to reset. When former F1 ‘ringmaster’ Bernie Ecclestone rolled out of the improper facet of mattress early in 2015 and declared the automobiles ought to be wider and extra aggressive-looking, he did this sporting class an excellent disservice as a result of the inevitable consequence was extra weight and made better problem in overtaking.
Wider, bigger-diameter wheels have additionally had an impact – one being mitigated barely for subsequent yr for the reason that entrance wheels can be 25mm narrower, the rears 30mm. Not a large quantity however, once more, there are efficiency concerns.
One change which might be politically tough to execute, however may scale back automobile weight, is to cut back aerodynamic and mechanical complexity.
“We are able to go in the direction of negating a few of the dimensional facets of automobiles, but it surely must be attainable to return again to a automobile that’s easier than it’s now,” mentioned Tombazis.

“And that’s an fascinating philosophical situation: why automobiles these days are much more sophisticated. The rationale folks design extra sophisticated automobiles is as a result of they’ve ‘near-perfect’ simulation functionality.
“Take the cooling system, for instance: automobiles prior to now used to have an entry duct and a radiator. After which the air after the radiator would discover its manner out via the bodywork and finally exit of the again. These days, there’s an entry duct, a radiator, and an exit duct, all absolutely profiled with little winglets and turning vanes.
“As one other instance, the entrance ground now has a damper and a full system to function at precisely the regulatory limits of deflection.
“So, there are lots of performance-increasing options on automobiles, all incremental, that make the automobile way more sophisticated – and heavier.”
It’s famously tough to return a genie to the bottle. No F1 staff would hand over an space of efficiency acquire with out a combat.
And that is the place the battle strains are forming forward of the 2026 season, as senior engineers have been overtly questioning whether or not the comparatively modest 30kg weight minimize deliberate for the brand new ruleset is even attainable. It’d – or ought to – be. And extra could be higher.
But when the development in the direction of weight acquire is to be meaningfully reversed, groups are going to have to surrender some long-cherished efficiency options.
